THE INTERNET

1. The internet allows users to send and receive emails, chat online, transfer computer to computer[using file transfer protocols-ftp's] and browse the web

   • Many companies use an intranet as well as the internet .
     • An intranet is defined as a computer network based on internet technology but designed to meet the needs for sharing information within a single organisation or company.
       • Access to an intranet is usually confined to a company an unlike the internet its not available to the general public.

2. Intranets reside behind a firewall and are only accessible by:

   • Internally to members of the company or to people given various levels of access who are external to the company.
     • Intranets are safer since there is less chance of external hacking or viruses.
       • Companies can ensure that the information available is specific to their needs it is easier to send out sensitive messages in the knowledge that they will remain within the company.

3. Intranets offer better bandwidth than the internet thus there are fewer connection limits than the internet.

   • It is possible to create Extranet that allows intranets to be extended outside the business but with the same advantages as an intranet.
     • This allows trading partners to have controlled access to some of the information.
